DEMOUNTABLE-BIM HOLDER.

Specification of Letters Iatent.

Patented Nov. 18, 1919.

Application filed May 6, 1919. Serial No. 295,170.

To all whom it may concern:

Be it known that I, Jnssn PRUE'IT Jacons, a citizen of the United States, .and a resident of Shelbyville, in thecou-nty of Bedford and State of Tennessee, have invented certain new and useful Improvements in Deniountablediim Holders, of which the following is a specificatiou' lilypresent invention relates generally to vehicle wheels and more nirtieularly to demountable rims, andhas for its primary object the provision of a holding arrangement capable of manipulation from a single point to either lock or release the rim in re.

spect to the wheelt'elly, instead of the individual manipulation of an annular series of rim holding lugs as now required.

A further object is the provision of an arrangement which will auton'iatically center the rim with respect to the wheel.

In the accompanying drawing illustrating my invention and forming a part of this specification,

Figure l is a side View;

Fif{. is an enlarged fragmentary side View;

Fig. 3 is a transverse section on line 3% of Fig. 2; and

Fig. 4- is an enlarged transverse section on line 4-4 of Fig. 1. K

Referring now to these figures, I provide the telly 15 of a wheel 16 with side grooves or rabbets atits outer periphery in which are rotatably seated the lug controlling rings 35 17, each having an inner rack face lfialong a portion thereof engaged by one of a pair of gears 19 mounted upon the opposite ends of a shaft 20 which, as seen particularly in Fig. 4, is journaled. transversely through the wheel telly, preferably in bushings 21. One end of this shaft 20 has a polygonal enlargement 252, so that the shaft may be conveniently rotated by means of an ordinary socket wrench (not shown), and the rings 17 simultaneously rotated.

At coin-distantly spaced points around the wheel-16, cross rods are extended latorally through the folly 15 and through the'inner endsof arcuateslots of the rim lugs 25 disposed in. pairs of which the lugs of each pair are o 'i'positc one another at the telly sides and are rigidly connected by a cross bar beyond the outer peripheral tare of the telly. The slots 2-1 of these rim lugs are also entered by studs 27 of the ringsl'r' and thus when the rings are shifted in one direction the entire series of lugs are moved correspondingly in an outward direction to the full line position of Fig. 2, their cross bars 26 pressing outwardly against the inner face o't'..the tire holding rim 27. The outer ends of the lugs 25 are thus positioned at the opposite sides of the rim 27 to prevent lateral shifting and dis placement thereo'l' uhtil the rings 17 are shifted in the opposite direction so as to rant the entire series of lugs inwardly beyond the inner face of the rim as seen in dotted lines in Fig. 2 when the rim is to'be remoi'ed.

It .is obvious, from the foregoing, that after the rim is placed properly on the wheel telly, for which pin-pose the lugs around one side are of greater length than the other to form rim abutments, the cross bars 26 of the several pairs of rocking lugs, will, in their movement outwardly against the rim, act as cams to wedge the rim in place and effectively center the same with respect to r the wheel.

In addition to the foregoing, it is to be lHKlBlStOOd, however, that the rim may be.

, wardly with respect to the telly 2. The combination of a wheel telly. having annular series of opposite side lugs pro-- vided with connecting cross bars disposed across the outer peripheral face of the folly, a demountable rim for engagement by said cross bars, and means for simultaneously shifting the series of lugs inwardly and outwardly with respect. to the telly, the lugs at one side of the telly having portions pro jecting a greater distance beyond the cross bars than the other lugs. for the purpose described.

3. The coml'nhation of a wheel folly havingannular series of opposite side lugs provided with connecting" cross bars disposed across the outerperipheral face of thefelly, a demountable rim for engagement by said cross bars. annular rings carried by the telly rim mini, 1'o,:i:ing lugs carried by the :felly at its opposite sides and connected across its pellpl l lill face, and means for simultaneously roelungihe said lugs into and out of active engagement with the rim.

5. The combination of a Wheel 'felly and rim, rocking lflgs carried by the felly at its oppoeite sides, said lugs being arranged opposite one another in pairs and each having angula 1: slots, a cross bar connecting the lugs of each pair outwardly beyond the telly, and cii'enmferentially shiftable rings carried by the telly and having studs extending into the i11 lots: for the purpose described.

6. The combination of a wheel. felly and rim, i'oeld ng lugs carried 'ley the fell yr at its opposite sides, said lugs being arranged 0pposite one another in pairs and each having angular slots, a cross bar connecting the lugs of each pair outward beyond the felly, said felly having annular side grooves, circumferentially shiftable rings seated in said grooves and having studs extending into the lug slots, said rings also having rack p01"- tions, and a shaft jo urnaled transversely throijlgh the fell-y and havin gearsthereon engaging the rack portions 0' the rings.
